2.-It is not necessary to make any air adjustment as the air is pre-adjusted by means of an air orifice in the Air Tube.
3.-A gas pressure regulator is a part of the Main Gas Valve of the Dishwasher which maintains correct gas pressure. The regulator is factory-set at 2.8" water column and should not have to be re-adjusted.
4.-The Gas Line is to be â…œ" Iron pipe or Copper tubing. The connection is â…œ" I.P.S. See paragraph 9 under "TO INSTALL DISHWASHER" on connecting the Gas Line. We recommend that an accessable shut-off valve be installed in the Gas Line before the con nection to the Dishwasher.
1.--The Dishwasher must have hot water supplied to it at between 20 and 120 pounds pressure per square inch, however, the temperature of the water is not important as the Preway Gas Dishwasher controls its own water temperature.
2.-Where local codes permit, Â½" O.D. minimum copper tubing may be used to connect the Hot Water to inlet on Service Connector. The connection size is â…œ" I.P.S. See paragraph 3 "TO INSTALL DISHWASHER" and the Template. This line may enter through the house floor or wall or from a near-by sink and should be equipped with an accessible shut-off valve.
Flush the hot water line before connecting to the Service Connector. This removes dirt, etc. which will prevent clogging the strainer screen in the Water Inlet Valve.
3.-The Drain Line must be connected to the drain outlet on the service connector with 1" pipe and may enter the house drain any place up to 18" above or below the floor level into the house drain system. Refer to Figures 4, 5, 6, 7, and 8.
A water trap is desired between the dishwasher and the house drain to prevent sewer odors from entering the home.
A drain air gap is a built in part of the Dishwasher Drain system.
However: If the built-in air gap cannot be used due to installation, plumbing codes, or desiring the entrance into the house drain above 18" from the floor level, the drain system must be changed. Refer to Figures 7 and 8.
The built-in air gap then must be eliminated and a short hose be substituted between the drain pump and drain outlet on the service connector. This 7" section of hose can be cut off from the original eliminated air gap line. See Figure 7. The plumber may then run the drain line from the service connector through an air gap installed at the height the local code requires, to a disposal unit or through a water trap to the house drain. See Figures 5, 6, 7, and 8.
4.-Be sure that all pipe or tubing is taper-reamed and is clean of chips, scale, white lead, lubricants, or other substances.

Typical Installation Into Disposal Unit Above 18" From Floor
1.-The Dishwasher is engineered to operate from a 115 volt, 60 cycle A.C. power source. The operating load is 6 amperes.
The Junction Box should be connected to the power supply with a separately fused circuit with a fuse rating of 15 amperes. All connections must be made to comply with local electrical codes.
If local codes require a separate Outlet Box, it could be installed in back of the Dishwasher or inside the adjoining cabinet at the right.
2.-The Dishwasher is completely wired and ready to be connected to the Power Supply with No. 14 2-wire (or 3-wire if desired for a ground wire) cable or conduit. Refer to local codes. The connection is made in the Junction Box in the right front of the Dishwasher. If coming from the rear, it can follow the Gas Line; if from the right side, it can come direct to the Junction Box through the cabinet side. See Paragraph 8 "TO INSTALL DISHWASHER" and Figure 1.
3.-A schematic Wiring Diagram is provided on the rear sfde of the Front Grille.
TO INSTALL DISHWASHER
1.-Remove the Service Connector from the rear base of the Dishwasher by unscrewing the two long Installation Bolts at the front just far enough so that the Service Connector is loose. Remove the service connector, Figure 9.
2.-Attach the Service Connector to the floor securely in the selected location and in accordance with the Template. If attached to wood floor, use 3/16" by 1 ¼" round head wood screws and if to concrete, use expansion fasteners.
Hot Water Connection Drain Connection
3.-Connect the Hot Water and Drain Lines to the Service Connector tightly.
4.-Run the Gas Line from the lower right rear so that the end of it is 5-1/16" from the front of the adjoining cabinets. The center of the gas line is 2¾" from the floor and 2" from the right side of the Dishwasher. This is important. See Template. Cap the end, turn on the gas and test all connections, for leaks. Use a soap solution for testing - never test with a match or open flame. If there are no leaks, shut off the gas and remove the cap from end of gas line.
5.-Slide the Dishwasher carefully into position against the Service Connector. Extreme care must be used in watching the Gas Line come through the Dishwasher
so that the Gas Line connections or any wiring are not disturbed. Be sure the slip-fit connections for the Hot Water and Drain Lines are pushed tightly in respective connections of the Service Connector. The Dishwasher must be level and aligned with the cabinets. It can be leveled by shimming under the front of the base or under the service connector.
6.-Screw the two Installation Bolts into the tapped holes in the Service Connector and draw up reasonably tight with a 4" wrench. It is not necessary to draw real tight as the "O" rings at the connections provide all seal necessary with a firm fitting of the Dishwasher against the Service Connector. The Installation Bolts are primarily used to hold the Dishwasher in place at the rear.
7.-Attach the right front end of the Dishwasher to the floor with one 3/16" x 1" wood screw, through the hole in the right front corner of the base. If concrete floor, use expansion fastener.
8.-Connect the lead-in wires or cable to the Junction Box of the Dishwasher. See Template and Figure 1. Connect the 4 white leads to white line of incoming power supply and black lead to black line of power supply. Solder the connections and wrap with tape.
If local codes require grounding other than that obtained by the water supply, grounding can be provided to the lug inside the Junction Box.
9.-To connect the Gas Line to the Dishwasher, shut off the gas to all other appliances. Unscrew the 6" nipple and elbow from the union and unscrew elbow from the nipple. See Figure 1. Screw Elbow onto the Gas Pipe tubing and screw the Nipple into the Elbow and then turn the Union onto the Nipple, carefully and tight. See that Safety Gas Cock is turned off . . . handle cross-wise to gas line. Turn on gas and again test all connections for leaks. When there are no leaks, turn Safety Gas Cock on - handle parallel with gas line.
Replace the Exhaust Tube: It snaps into Dilution Chamber in the rear and fits over the two screw ends protruding through the leg on the right side. Secure into position with the two 3/16'' hex head screws.
10.-Now operate the Dishwasher one complete cycle to test all connections for leaks. See separate instructions. Be sure there are no foreign objects inside the Dishwasher and that the dish racks are in place. The Front Grille will have to be installed for the test cycling so that the Grille Safety switch will be closed.
11.-If there are leaks in the Drain or Hot Water connections, push Timer in to stop the cycle. This shuts of cycling action. Remove the Front Grille and tighten connections to stop leaks. If there are no leaks, replace the Front Grille and install the Toe Plate.
12.-The Dishwasher is now ready to be placed in operation. See separate instructions.
13.-The countertop can now bt installed directly over the Dishwasher if it is not already in place.
14.-It is unnecessary to vent this dishwasher to the outside.
15.-We accept no responsibility for the installation or the connection of the Dishwasher to the Service Lines.
